T() ALL WHOM IT MAY CONCERN:

Be it known that we, JAMES J. Gnnvnn and AMBnosE D. WIGGINs, of New Market, State of Ohio, have invented certain new and useful Improvements in Churns; and we declare the t'ollowing'to be a full, true, and

exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure lis a perspective View of our invention.

Figure 2 is a plan viewof the bed-piece for the churn.

Figure 3 is a. side elevation ofthe lower part ofthe churn. v

To enable others skilled in the art to make and use our invention, we will now describe its construction and opera-tion. v

A A are two uprights, let into sills B B, and supported by props C C. D is n cross-piece, which connects the two uprights A A nt the top. E represents the bed-piece, held between the sills B B. The said bed-piece is provided with a. slot, as shown in fig. 2. F is the churn, the bottom of which has a projection or tenen, lf., as v seen in g. 3. This tenen rests in slot or mortise in hed-piece E, and serves to keep the churn steady while in` operation. aia are the dashers, provided with holes. b b represent the dusher-bars, which are connected to` the double crank-shaft-d lby means of the pitmen e e. The seid `pi'tmen are made adjustable tolthe dusherbars, as v seen in fig. 1. On one end the crank-shaft d is thc fly or balancewheelf. On the opposite end is the pinion g, which gears in the driving-wheel h. K is the crank, by means of which motionis given to crankshaft d. m represents an adjustnble guide-hoard, through which the da-sher-bers b work.

The operation of our churn is so apparent that no description of it is required.

What We claim, and desire to secure by Letters Patent, is-

v The slotted bed-piece E, churn F, when provided with tenon h, and adjustable guide-boord. m, all` arranged in connection with dasher-bars b b, pitmen e e, and double crank-shaft d, as and for the purpose set forth.

In testimony that we claim the nl )ove as our own we affix our signatures in presence of' two witnesses.
